Hi, Python date time experts,
summary for getting UTC time in sec:
print time.time()
print calendar.timegm(time.gmtime())
print time.mktime(time.localtime())
print calendar.timegm(datetime.datetime.utcnow().timetuple())
print time.mktime(datetime.datetime.now().timetuple())
Are all the functions above expected?
See code below:
